    We are constructing a new concrete block double garage and the Architect has specified a Catnic lintol for the 3.6m wide opening. However, our builder feels that this is overkill and a conventional H beam steel lintol is adequate. The project has secured Building Consent from local planning although there has been no requirement for input from a Structural Engineer as part of the process. Which is more suitable for the job?

    Whatever the cheapest and structurally capable lintel is the one most suitable for the job, however a catnic lintel may be the better option depending on how you envisage finishing off the outer face of the wall in front of the lintel

    The outer face of the garage will be finished with 19mm roughcast.
     
  5. Would go for a Catnic, you can have blocks or bricks built straight onto the Catnic, which can then be Roughcast straight onto.
    With an RSJ it would need to blocks of wood inserted, then meshed for the roughcast, which is also more work and materials you do not already havy on site.
